Sigma Radiator fan wiring - Is this normal?
Jonathan Kay replied to Northern Banana's topic in TechTalk
"When cold and the fan not running I get 12v at the fan plug, when it reaches 97 and gets the signal from the ECU it reads 12.5-13.5v is that slight increase in voltage what switches on the fan?" Where are you putting the other probe? And what colours are the wires to the fan motor? Jonathan -

Drilling the 3 holes for a new Momo steering wheel

Previous discussion. I can't find a template. Jonathan -
"... I would not expect to see 12v while the engine is cranking, given the small battery. It is likely to be nearer 10v." I'd be concerned about the state of the battery by anything below 10.5 V while cranking. And some electronics on some Sevens gets unhappy. Jonathan

Well done. Thanks for the update. And check that loading at the brackets as you remove it! Jonathan

As above. Please let me know if you'd like a copy of the Assembly Guide. Jonathan

"It would also be worth checking the earth side for continuity." Yes. And before removing the pump I'd run a good feed and earth directly to it. Jonathan

As above. But if it's a metal can type you can also transfix it with a screwdriver and then use that as a lever. Jonathan

I try to avoid any sealing compounds for radiators or hoses. Jonathan

Yours doesn't look like the same sort of fault that has recently affected so many aluminium radiators. But I'd still check that there aren't any twisting or bending forces on the radiator from the mountings. It should clamp up nicely without these forces and you can check when you take it out.

One Member has a radiator blind controlled from the cockpit... Jonathan

I'd get it out and inspected by whoever might repair it if that's possible. Recent discussion of a similar problem. NB Safety precautions: the petrol vapour lingers. Jonathan

"Alternator on my 2002 K series road sport is not charging at a level to make the red light go out. Checked with meter, not reaching 11 volts and does not alter with higher revs." It does sound as if it's duff. But check the connectors and the wiring, including the engine block earth, before anything expensive. Please let me know if you'd like a wiring diagram. Jonathan

"Does anyone know the part number for ,I suppose the standard rover replacement part." First I'd try and identify the family. Can you see any markings on it and what's the terminal layout? Jonathan

What Ian says: they're surprisingly repairable and that way both the brackets and wiring will fit. Jonathan
